Want to run custom software in your Alltek board? It's just a concatenation of the freely available rom files in one large binary.

Below is a csv file you can open in excel or open office etc. anything that will read a spreadsheet.... detailing the current rom map as identified by pinmame, with the offset etc. in there. (cut and paste it into a blank notepad document and save as .csv - csv files not allowed as attachments here)

Some of the freeplay variants etc. that are not in pinmame will just be listed as unknown, as well as some other software that's just not in pinmame. There are a couple anomalies between the official alltek dip settings and what gets ID'd by pinmame.

It's not hard to see the pattern of dip settings and how they correspond to the addresses. You could also just burn a new eprom for it into one of the blank areas. Of course, you will have to read in your own eprom yourself, since Alltek doesn't share it due to licensing.
